Feeling they haven't done enough during their summer vacation, Miyuki suggests they take advantage of the Library of Legends to travel around the world. The girls take a trip through various locations such as Versailles, Taiwan, Mongolia, the Great Wall of China and New York City. As the girls wrap up their trip in the Amazon, they are confronted by Akaoni who extracts negative energy from the wildlife while having a Pirhana Super Akanbe swallow Candy and the Decor Decor. With the girls struggling underwater, Candy uses the Dolphin Decor to turn them into mermaids to rescue her before they defeat the Akanbe for the last Cure Decors they need. Upon completing the Decor Decor again, a mysterious new clock appears.
